Buying advice

When selecting cup washers, consider the environment (indoor vs outdoor), required corrosion resistance, and load requirements. Stainless steel offers the best durability for wet or corrosive conditions, while zinc-plated or plain steel are cheaper for dry indoor use. Ensure the inner diameter matches your screw or bolt size and the outer diameter provides enough bearing surface.
